Features

• Computing of relative deltas (next month, next year, next Monday, last week of month, etc);
• Computing of relative deltas between two given date and/or datetime objects;
• Computing of dates based on very flexible recurrence rules, using a superset of the iCalendar specification. Parsing of RFC strings is supported as well.
• Generic parsing of dates in almost any string format;
• Timezone (tzinfo) implementations for tzfile(5) format files (/etc/localtime, /usr/share/zoneinfo, etc), TZ environment string (in all known formats), iCalendar format files, given ranges (with help from relative deltas), local machine timezone, fixed offset timezone, UTC timezone, and Windows registry-based time zones.
• Internal up-to-date world timezone information based on Olson's database.
• Computing of Easter Sunday dates for any given year, using Western, Orthodox or Julian algorithms;
• A comprehensive test suite.

Quick example

Here's a snapshot, just to give an idea about the power of the package. For more examples, look at the documentation.

Suppose you want to know how much time is left, in years/months/days/etc, before the next easter happening on a year with a Friday 13th in August, and you want to get today's date out of the "date" unix system command. Here is the code:

>>> from datetime import *
>>> from dateutilx.easter import *
>>> from dateutilx.parser import *
>>> from dateutilx.relativedelta import RelativeDelta
>>> from dateutilx.rrule import *
>>> 
>>> now = parse("Sat Oct 11 17:13:46 UTC 2003")
>>> today = now.date()
>>> year = rrule(YEARLY, dtstart=now, bymonth=8, bymonthday=13, byweekday=FR)[0].year
>>> rdelta = relativedelta(easter(year), today)
>>> print("Today is: %s" % today)
"Today is: 2003-10-11"
>>> print("Year with next Aug 13th on a Friday is: %s" % year)
"Year with next Aug 13th on a Friday is: 2004"
>>> print("How far is the Easter of that year: %s" % rdelta)
"How far is the Easter of that year: RelativeDelta(months=+6)"
>>> print("And the Easter of that year is: %s" % (today + rdelta))
"And the Easter of that year is: 2004-04-11"

Being exactly 6 months ahead was really a coincidence :)
